One usefuloption for the composition of the exercise machine 10 may, for example,include carbon steel.

The shaft 2 is the central piece and backbone for strength, stability,and durability for the exercise device 10. The shaft 2 is connected to afront foot 22, a seat 8, a rear beam 16, and a collapsible beam 9 asshown. The shaft 2, front foot 22, rear foot 18, or the rear beam 16 maybe of a variety of lengths, shapes and sizes, depending upon the usersneeds. One useful option for the shaft 2 may include either a straightor curved shaft with very strong and rigid 1.50″×1.50″ inch square steeltubing resistant to the wear and tear of the motion of the trolley 4.

In one embodiment, the seat 8 may be a large, stable, and comfortableseat 8, semi-permanently or permanently connected to the rear end of theshaft 2. The seat 8 may be of any type of rubber, plastic, foam, fibroussubstance, cloth, synthetic material, or any other type of materialknown in the art, which are suitable for such an application.

In one embodiment, the shaft 2 has a front end and a rear end. The frontend is attached via a connection device 21 to a front foot 22 forstability and stabilization. The connection device 21 may include angledbrackets, mounting clamps, or other type of connection devices known inthe art for attaching structures together, and may be a separatecomponent or as a permanent structure to either the shaft 2 or the frontfoot 22.

In one embodiment, the exercise device 10 allows the trolley 4 to rollalong the shaft 2 in a forward, backward, upward, downward, or any otherdirectional motion. The trolley 4 consists of a peg 6 connected to thevertical plates 32. Multiple pegs 6 may connect to the trolley 4. Thetrolley 4 may include adding additional free or external weights to thepeg 6. Each of the vertical plates 32 is placed on opposite sides of theshaft 2. The wheels 20 of the trolley 4 are connected to each of thevertical plates 32. One useful option may include two wheels 20connected to upper portion of the vertical plates 32. The trolley 4third wheels 20 may connect to each of the lower portion of the verticalplates 32 and be underneath the shaft 2. The two top wheels 20 of thetrolley 4 may span the width of the shaft 2 and roll along the top ofthe shaft 2. The third wheels 20 of the trolley 4, located on the lowerportion of the vertical plates 32, may also span the width of the shaft2 but may or may not come in contact and roll along the shaft 2. Theshaft 2 includes various openings 38 allowing for the use of a ball lockpin, or other device commonly known in the art, allowing the trolley 4to be positioned along the shaft 2 in various locations to accommodatevarious users' leg lengths. The various openings 38 may be placedthroughout the shaft 2 and may include multiple various openings 38.

In one embodiment, the peg 6 allows the user to place on, beneath,inside, above, or securely fix the users feet to the peg 6 to pull thetrolley 4 along the shaft. The peg 6 may include attachment devices,such as Velcro®, straps, pedals, or other devices to fix to users feetonto the peg 6. One useful option may include the shaft 2 angled upwardstowards the user, and with the users feet on the peg 6 of the trolley 4,pull the trolley 4 along the shaft 2 upwards along the shaft 2 until theshaft 2 reaches a desired ending position or the top of the shaft 2.Once the trolley 4 is at the peak or furthest closest position to theuser, the trolley 4 may stop and roll down the angled shaft 2 to theoriginal starting position for another repetition. For example, thetrolley 4 may roll down the shaft by gravity, the flexible cord 14, theusers feet, or a combination of gravity, the flexible cord 14, and theusers feet.

In one embodiment, the rear end of the shaft 2 is connected, by a bolt15, to the seat 8 and the collapsible beam 9. The bolt 15 may includeany connective means such as a bolt, nail, screw, pin, rod, or otherdevice commonly used in the art for connection. The collapsible beam 9contains both an upper collapsible beam 13 and a lower collapsible beam12. The upper collapsible beam 13 connects to the shaft 2 while thelower collapsible beam 12 connects to the rear beam 16. The collapsiblebeam 9 may either be designed as one singular piece, or the collapsiblebeam 9 may centrally connect two separate attachment pieces, by means ofthe bolt 15 located in the center of the collapsible beam 9, so as toallow the collapsible beam 9 to pivot, extend, and collapse. Either as asingular piece or two separate pieces, the collapsible beam 9 may pivot,extend, or collapse. A slider 5 is a mechanism used to lock thecollapsible beam 9 when the machine is in a set up, a ready, or anupright position. The slider 5 is capable of sliding along thecollapsible beam 9. The slider 5 may be a coupling device or housingdevice that surrounds the collapsible beam 9. When the slider 5 is overthe bolt 15 in a locked position, the collapsible beam 9 is unable topivot, bend, or collapse. In other words, when the collapsible beam 9 isin a substantially straightened position, the slider 5 may slide alongthe collapsible beam 9 and be set to a locked position over the bolt 15,which is located in the center of the collapsible beam 9. The lockedposition of the slider 5 allows the user to be in a seated position onthe exercise device 10 with the shaft 2 in an angled position and therear beam 16 in an upright position to stabilize and support theexercise device 10.

Hooks 28 are attached to rings 44, which are secured to the front foot22 and rear foot 18. The hooks 28 attach to the rings 44 providing theoption for flexible hand held cords 24 to be used by the user's handsfor additional support, resistance, stability, exercise or other variousneeds for using the exercise device 10. Additional features, asdescribed in earlier figures, are also depicted as illustrated examples.

Turning to FIG. 2, in one embodiment, again the exercise device includesa shaft 2 with a trolley 4 for rolling along the shaft 2. The rear orright end of the shaft 2 is connected to the seat 8 and the collapsiblebeam 9 by a bolt 15. The collapsible beam 9 contains both an uppercollapsible beam 13 and a lower collapsible beam 12. The uppercollapsible beam 13 connects to the shaft 2 and the lower collapsiblebeam 12 connects to the rear beam 16. The collapsible beam 9 may eitherbe one piece or the collapsible beam 9 may centrally connect twoseparate attachment pieces, by means of the bolt 15, the bolt 15 beingany connective means such as a bolt, nail, screw, pin, rod, or otherdevice commonly used in the art for connection, so as to allow thecollapsible beam 9 to pivot, extend, and collapse. The shaft 2 has afront or left end where the shaft 2 connects to the front foot 22 by aconnection device 21.

More clearly depicted in FIG. 2, is one example of several bolts 27connecting the seat 8 to the attachment pieces 30 which connect to theshaft 2, the bolts 27 may be any connective means such as a bolt, nail,screw, pin, adhesive, or other device commonly used in the art for suchconnective purposes.

The front foot 22 may contain end caps 29 on each end to further providesecurity, stabilization, and protection of the exercise device 10. Moreclearly depicted is the flexible cord 14, which connects to the trolley4. The flexible cord 14 may connect directly to either one or both ofthe vertical plates 32 or a connective pin 84 that is connected to thelower half of the vertical plates 32. One useful option provides for theconnective pin 84 device to connect to the lower half of each of thevertical plates 32. The connective pin 84 may span the width, beneaththe lower half, of the shaft 2. The exercise device 10 enables the userto select multiple flexible cords 14 or a single flexible cord 14 forresistance to vary the trolley 4 speed, resistance, stroke, andposition. The flexible cord 14 is connected to a pulley 25 justunderneath the shaft 2 near the connecting device 21. The flexible cord14 rotates around the pulley 25 and travels back towards the right endof the shaft 2 to connect to the shaft 2 just underneath the shaft 2 andthe seat 8. The flexible cord 14 may also use the lower wheels 20 of thetrolley 4 as an additional pulley. Depending upon the amount of weightthe trolley 4 supports, a slight gap between the bottom of the shaft 2and the lower wheels 20 of the trolley 2 may exist. The lower wheels 20of the trolley 4 may work also as an additional pulley for the flexiblecord 14. For example, as the user is pulling the trolley 4 along theangled shaft 2 in an upward direction, the wheels 20 underneath theshaft 2 will spin in an opposite direction than the wheels 20 on thetrolley 4 above the shaft 2. The wheels 20 of the trolley 4 underneaththe shaft 2 will rotate, in the direction of the flexible cord 14,acting like a pulley.

In one embodiment, a side view of the collapsible beam 9 is more clearlyobserved. The upper collapsible beam 13 connects to the shaft 2 by thebolt 15, the bolt 15 being any connecting device such as a bolt, nail,screw, or other known adhesive commonly known in the art suitable forsuch purposes. The lower collapsible beam 12 is connected to the rearbeam 16 with the bolt 15. In the center of the collapsible beam 9, thebolt 15 acts as a pivot structure allowing for the upper collapsiblebeam 13 and the lower collapsible beam 12 to rotate, pivot, extend, andpivotally move about the bolt 15. Additional features, as described inearlier figures, are also depicted as illustrated examples.

Turning to FIG. 3A and 3B collectively, depicts more clearly theexercise device 10 in an exemplary embodiment from a front view, FIG.3A, a side view FIG. 3B. As seen in both the front view and side view,in one embodiment, again the exercise device includes a shaft 2 with atrolley 4 for rolling along the shaft 2. The rear or right end of theshaft 2 is connected to the seat 8 and the collapsible beam 9 by a bolt15. One example may include several bolts 27 connecting the seat 8 tothe shaft 2, the bolts 27 being any connective means such as a bolt,nail, screw, pin, adhesive, or other device commonly used in the art forsuch connective purposes. The collapsible beam 9 may either be one pieceor the collapsible beam 9 may centrally connect two separate attachmentpieces, by means of the bolt 15, the bolt 15 being any connective meanssuch as a bolt, nail, screw, pin, rod, or other device commonly used inthe art for connection, so as to allow the collapsible beam 9 to pivot,extend, and collapse. The shaft 2 has a front or left end where theshaft 2 connects to the front foot 22 by a connection device 21.

In one example, both the front and side view illustrate that thecollapsible beam 9, containing both the upper collapsible beam 13 and alower collapsible beam 12 being connected to the shaft with the bolt 15,but a spacer 3 is utilized to provide a distance between the collapsiblebeam 9 and the shaft 2. The spacer 3 allows the collapsible beam 9 toextend, collapse, and for the slider 5 to move up and down thecollapsible beam 9 without any contact with the shaft. The spacer 3allows for the exercise device 10 to be set up or taken down with easeand simplicity. The spacer 3 may be of any type of material commonlyused in the art for providing spacing and a buffer zone between theshaft and the upper collapsible beam 13 and the lower collapsible beam12. The seat 8 also provides a seat handle 26 for gripping and holdingon the to seat during exercise or for moving, lifting, holding, andtransporting the exercise device 10.

In one exemplary embodiment, in both the front view and the side view,the wheels 20 of the trolley 4, which connect to the vertical plates 32,span the width of the shaft to a degree that vertical plates 32 are setout past the shaft 2. The spacing between the shaft and the verticalplates 32 allows for the trolley 4 to smoothly roll along the shaft.Additional features, as described in earlier figures, are also depictedas illustrated examples.

Turning to FIG. 4, an exemplary embodiment is depicted from the top viewof an exercise device 10. The assembled exercise device 10 illustratesfrom a top view the top portion of the seat 8 and the seat handle 26attached to the shaft 2. Further depicted, is the front side of theshaft 2 being attached via a connection device 21 to a front foot 22 forstability and stabilization. The front foot 22 may be straight, curved,or other geometric shape. The hooks 28 are attached to rings 44 whichare secured to the either the front foot 22 and rear foot 18, both ofwhich may include the rings 44 positioned at various locations on thefront foot 22 or the rear foot 18. The hooks 28 attach to the rings 44providing the option for flexible hand held cords 24 to be used by theuser's hands for additional support, resistance, stability, exercise orother various needs for using the exercise device 10. The flexible handheld cords 24 may include a variety of handles commonly used in the artfor providing a structure that holding or connecting to a rope. Theflexible hand held cords 24 may be designed with differing strengths,lengths, materials, and resistance capabilities. The flexibility handheld cords 24 may easily attach and be removed from the rings 44 usingthe hooks 28. Additional features, as described in earlier figures, arealso depicted as illustrated examples.

Turning to FIG. 5 an exemplary embodiment depicts a three-dimensionalview lower and back view of seat 8 connected to the shaft 2. As depictedin this example, the seat 8 has two substantially planar or horizontalsurfaces; a top surface for seating upon the exercise device 10 and abottom surface for connecting to the shaft 2. As illustrated from theback view looking at the bottom surface of the seat 8, the thickness ofthe seat 8 from the top surface to the bottom surface may vary dependingupon the type of seat 8. The seat 8 may be made of any type of materialfor sitting, as commonly used in the art for sitting to accomplish suchpurpose. The seat 8 may have a handle attached to the rear of the seat8, either assembled as a separate attachment or may be formed andcreated as one piece at the time of the creation of the seat 8. Thebottom surface of the seat 8 is connected to the shaft 2 withtwo-attachment piece 30. Depicted as opposites in construction. Theattachment piece 30 may be a separate connective piece used to connectthe seat 8 to the shaft 2, or, in the alternative, the shaft 2 and theattachment piece 30 may be constructed as one singular piece.

As depicted in this example, the attachment piece 30 is separate fromthe shaft 2 and the seat 8. The rear end of the shaft 2 connects to theattachment piece 30 by bolt 15 and bolts 17. The attachment piece 30 isdesigned with a top surface that is substantially planer andsubstantially parallel with the seat 8. The attachment piece 30 has twosides that run from end to end, the height or depth of the left sidebegins to angle downward and longer than on the right side of theattachment piece 30. The angular depth of the longer left side allowsthe shaft 2 to fit into the attachment piece 30, the angle of the leftside being nearly identical with the angle of the shaft 2. The right endof the attachment piece 30 includes additional depth for connecting theattachment piece 30 to the rear beam 16. The attachment piece 30 mayconnect to the shaft 2 on the left side of the attachment piece 30, theseat 8 on the top surface of the attachment piece 30, and the rear beam16 on the right side of the attachment piece 30. On the top surface ofthe attachment piece 30, the seat 8 sits flush with the shaft 2 and isconnected to the attachment piece 30 with the connecting bolts 27. Thenumber of connecting bolts 27 may vary with the size, shape, and variousdimensions of the seat 8. The attachment piece 30 connects to the rearbeam 16 by a bolt 19. The attachment piece 30 and the seat 8 may beconstructed and positioned allowing the option of adding an additionalpulley under the seat 8. The additional pulley allows the option toconnect the flexible cord 14 to the front foot 22 in a fixed position.For example, the flexible cord being connected to the front foot 22 mayconnect to the additional pulley under the seat. The additional pulleyprovides the flexible cord 14 to travel back down along the shaft 2 andattaching to the trolley 4. Reversing the attachments of the flexiblecord 14 provides the capabilities for the user to start the trolley 4near or at the top of the shaft. The user may then push downward on thepeg 6 of the trolley 4 towards the ground with resistance to the personlegs. Additional features, as described in earlier figures, are alsodepicted as illustrated examples.

Turning to FIGS. 6A and 6B, an exemplary embodiment depicts athree-dimensional view a trolley 4 and the wheels of the trolley 4. Theembodiment in FIG. 6A illustrates one example of the trolley 4 assembledtogether with the wheels 20 attached, and in FIG. 6B one exampleillustrates the wheels 20 of the trolley 4.

Turning to FIG. 6A, in the depicted embodiment the trolley 4 is formedby using two vertical plates 32 and three wheels 20. The vertical plates32 may be designed using a variety of shapes, sizes, and materials,commonly known in the art to accomplish such purpose. One useful optionmay include the vertical plates 32 to be designed so the upper portionof the vertical plates 32 may connect or attach the two wheels 20 toeach end of the upper portion of the vertical plates 32. In the centerof the upper portion of the vertical plates 32 a structural pin 88 maybe inserted for structural integrity, support, and stabilization of thetrolley 4. The structural pin 88 may be a separate piece or may be adesigned and manufactured as one singular piece; the two vertical plates32 and the structural pin 88 being one singular piece with the wheels 20to be attached separately.

Each of the vertical plates 32 may include openings for the wheels 20and the structural pin 88 to be attached with any pin, bolt, peg, nail,screw, dowel, shaft, drill blank, or any other connective devicecommonly used in the art to accomplish such purposes. This method ofattachment may be either temporary such as bolt and nut or permanentsuch as welding or a press fit. The vertical plates 32 may include athird wheel 20 to be attached and connected to the lower portion of thevertical plates 32. The wheels 20, being connected to the upper portionof the vertical plates 32, may span the width of the top portion of theshaft 2 and assist in rolling the trolley 4 along the shaft 2. Thewheels 20, being connected to the lower portion of the vertical plates32, may roll along the bottom of the shaft to assist the trolley 4moving along the shaft 2. Alternatively, the wheels 20 connecting to thebottom portion of the vertical plates 32 may also assist the flexiblecord 14 by serving as an additional pulley for the flexible cord 14. Forexample, depending upon the amount of weight placed upon the trolley 4,the wheels 20, connected to the lower portion of the vertical plates 32,may not touch or roll along the shaft 2. Rather, sufficient spacingexits between the bottom of the shaft 2 and the bottom wheels 20 of thetrolley 4. The wheels 20 on the bottom portion of the vertical plates 32may be free spinning acting as a pulley for the flexible cord 14; thebottom wheels 20 of the trolley 4 may be spinning in the same directionas the flexible cord 14 and opposite the direction of the top wheels 20of the trolley 4.

The bottom portion of the vertical plates 32 may include a connectivepin 84 for attaching the flexible cord 14 to the trolley 4. Theconnective pin 84 may be a separate piece or may be a designed andmanufactured as one singular piece, meaning the two vertical plates 32and the connective pin 84 being one singular piece with the wheels 20 tobe attached separately. The connective pin 84 may be any pin, bolt, peg,nail, screw, or any other connective device commonly used in the art toaccomplish such purposes. If the connective pin 84 is a separate piece,the connective pin 84 be removed, interchanged, and replaced. Varioustolerance levels may be determined by the type, shape, and durability ofthe material of the connective pin 84 for supporting and providingresistance to the flexible cord 14. One or multiple flexible cords 14may be attached to the connective pin 84.

Turning to FIG. 6B, in the depicted embodiment, the wheels 20 of thetrolley 4 are more clearly displayed. The trolley 4 may use a total ofthree wheels 20. The design of the wheels 20 may use threedouble-flanged wheels for the trolley 4 spanning the width of the shaft2. The wheels 20 may be a spool design with a variety of materials forminimizing rolling resistance while providing support for the trolley 4.The wheels 20 may have wheel edges 40 that are higher on the sides thanin the center of the wheels 20. The material for the wheels may include,but not limited to, plastic, fiber, fiberglass, carbon fiber, composite,polymers, sponge, metal, or any other type of material or combination ofmaterials commonly know in the art for a wheels to accomplish suchpurposes. The wheels 20 may include a centerpiece 42, which may includemore than one bearing, bushings, or other devices for assistance inrolling as commonly used in the art. Such designs may eliminatetolerance stacking and simplifies fabrication and assembly costs. Thewheels 20 may include a center opening for a pin, screw, bolt, or otherdevice commonly used in the art. The wheels 20 may be machined inside tovarious tolerances and bearing depths. One useful example may includethe bearings positioned inside of the wheels 20 adapted to avoid ridingon the threads of a bolt or pin to prevent fretting.

Turning to FIG. 7, in the depicted embodiment the trolley 4, shaft 2,and the front foot 22 are more clearly displayed. In one embodiment, theshaft 2 has a front end. The front end is attached via a connectiondevice 21 to a front foot 22 for stability and stabilization. Theconnection device 21 may include angled brackets, mounting clamps, orother type of connection devices known in the art for attachingstructures together, and may be a separate component or as a permanentstructure to either the shaft 2 or the front foot 22.

It should be noted that in the event of more than one wheel 121 (e.g.,one ore more roller blade wheels), the 2 bolt axles 122 do not runparallel to each other because it makes the wheels 121 bind. The boltaxles 122 need to be at a slight angle (which may vary according todesign and user preference) to each other. That angle is determined bythe general length of the shaft in relation to the average pivot pointof the flexible mechanism 100 (e.g., a spring). In other words, whenboth wheels 121 are touching the ground, if the user swings the shaft 2to the left and/or to the right, the exercise device, more specificallythe shaft 2, essentially makes an arc or circle. Nominally, each wheelis aligned to the circle tangency that would be created by swinging saidarc.
